By adding a timeout commaNd to your batch file you can have it change dreams without using the event timer.
For example, TIMEOUT /T 3600, will sleep the bat file for 1 hour.
You can do something like: I store my dreams in C:\DREAMS.
C:\Dreams\EARTHRISE.DREAM
TIMEOUT /T 3600
C:\Dreams SEASCAPE.DREAM
...
Etc.
By the way, do not hit enter when you see the prompt unless you want to bypass the timer and immediately go to the next dream.
You can also do this with a VBS script which will allow even more flexibility.
